NOISE CANCELLING SOUNDBAR DEVICE AND SYSTEM
A noise cancelling soundbar that may be integrated into a piece of furniture, such as a bed, comprising one or more loudspeakers, an integrated power amplifier, one or more microphones, an audio input communication module, and an active noise cancellation module. After receiving an audio input signal from a media source, such as a TV or smartphone, the noise cancelling soundbar may produce an amplified output signal. By using its microphones and active noise cancellation technology, the noise cancelling soundbar may, in addition to reproducing input audio via its loudspeakers, generate negative sound waves which destructively interfere with ambient noise to allow users to listen to audiovisual media without disturbing non-listeners in the area, and without using headphones.
System for rendering and playback of object based audio in various listening environments
Embodiments are described for a system of rendering object-based audio content through a system that includes individually addressable drivers, including at least one driver that is configured to project sound waves toward one or more surfaces within a listening environment for reflection to a listening area within the listening environment; a renderer configured to receive and process audio streams and one or more metadata sets associated with each of the audio streams and specifying a playback location of a respective audio stream; and a playback system coupled to the renderer and configured to render the audio streams to a plurality of audio feeds corresponding to the array of audio drivers in accordance with the one or more metadata sets.
NOISE-CANCELING HEADPHONES INCLUDING MULTIPLE VIBRATION MEMBERS AND RELATED METHODS
Noise-canceling headphones may include a headband, an audio input, and earcups supported proximate ends of the headband. A first vibration member operatively connected to the audio input, a second vibration member operatively connected to the audio input, and a microphone may be supported by a housing of at least one of the earcups. A feedback, noise-cancelation circuit configured to reduce a user's perception of a portion of an audible response of the second vibration member may be operatively connected to the microphone. The feedback, noise-cancelation circuit may be configured to modify an audio signal from the audio input at least in part based on a signal from the microphone and send the modified audio signal to the first vibration member.
HEADPHONE SPEAKER SYSTEM WITH INNER-EAR AND OVER-THE-EAR SPEAKERS
A headphone speaker system includes over-the-ear speakers (left and right) and inner-ear speakers (left and right). The left over-the-ear speaker and the right over-the-ear speaker are configured to receive a left surround audio channel of an audio signal and a right surround audio channel of the audio signal, respectively, from a surround sound processor, and are configured to be positioned outside a left ear canal of a user and outside a right ear canal of the user, respectively. The left inner-ear speaker and the right inner-ear speaker are configured to receive a left front audio channel of the audio signal and a right front audio channel of the audio signal, respectively, from the surround sound processor, and are configured to be positioned at least partially within the left ear canal of the user and at least partially within the right ear canal of the user, respectively.
Audio signal processing device and sound box
An audio signal processing device, including: a digital signal processing module, an input module, an output module, and a control module. The digital signal processing module is in connection with the input module and the output module, and the control module is in connection with the output module. The output module includes at least two output channels, with each output channel including a power amplifier and a speaker in series connection. The digital signal processing module is configured to receive an audio signal output by the input module and to process the audio signal with at least two different audio processing algorithms, and output the at least two audio processing signals. Each audio processing signal corresponds to one output channel. The control module is configured to control the operation state of the power amplifier of each output channel and the magnification thereof in operation.
Eyeglass headphones
An eyeglass headphone with a frame that is constructed and arranged to be carried by the head of a wearer, the frame comprising a bridge that is adapted to be supported by the wearer's nose, and a left temple and a right temple that extend rearwardly from the bridge, toward the left and right ears of the wearer, respectively, and a dipole loudspeaker built into the frame, where the dipole loudspeaker comprises a driver that emits front-side acoustic radiation from its front side, and emits rear-side acoustic radiation from its rear side. The frame comprises at least first and second sound-emitting openings, wherein the first sound-emitting opening is constructed and arranged to emit front-side acoustic radiation and the second sound-emitting opening is constructed and arranged to emit rear-side acoustic radiation.
Microphone Placement in Open Ear Hearing Assistance Devices
A head-worn acoustic device includes at least one acoustic transducer disposed such that, in a head-worn state, the transducer is in an open-ear configuration in which an ear canal of a user of the head-worn acoustic device is unobstructed. The acoustic device also includes at least one microphone configured to capture audio that is processed and played back through the transducer, and an amplifier circuit configured to process signals representing the audio captured using the microphone and generate driver signals for the transducer. The transducer and the microphone are disposed on the head-worn acoustic device such that, in the head-worn state, a lobe of a radiation pattern of the at least one acoustic transducer is directed towards the ear canal of the user, and the at least one microphone is positioned in an acoustic null in a radiation pattern of the at least one acoustic transducer.
Headphone Device for Reproducing Three-Dimensional Sound Therein, and Associated Method
3D audio virtualization within headphone-type sound reproduction devices, comprises: deriving an HRTF, comprising a PRTF, that includes acoustical effects due to pinnae and ear canals, and a remainder HRTF, that includes acoustical effects due to head, shoulders, torso and other body parts while excluding acoustical effects from pinnae and ear canals; wherein the remainder HRTF is electronically implemented and omits acoustical effects due to pinnae and ear canal effects; and wherein the PRTF is acoustically implemented and personalized to the user through use of two or more transducers positioned such that a front plane of the transducer, the front plane of the transducer's diaphragm, the transducer's mechanical center or the transducer's acoustical center point are 25 mm or more from a user's ear canal entrance, and/or oriented so the 0 axis of acoustical output is aligned with the acoustical output axes of typical external loudspeakers positioned in the acoustical far-field.
Loudspeaker and sound outputting apparatus having the same
A sound outputting apparatus is provided. The sound outputting apparatus includes at least one loudspeaker, and a main body configured to house the at least one loudspeaker. Each of the at least one loudspeaker includes an acoustic transducer configured to generate a sound wave, and a sound guide part configured to directionally output the sound wave via a plurality of openings. A diameter of each of the plurality of openings is increased as a distance from the acoustic transducer increases.
IN-EAR HEADPHONE
A low-profile earbud is disclosed that sits securely within an ear of a user. The earbud includes a protruding portion that passes through a channel defined by the tragus and anti-tragus of the ear.
